Rome was sacked multiple times, and it was hit with disease. Due to the constant warfare and disease, most of the population either died or left the city. Because of this, the population had such a drastic decrease.

Another reason had to do with the grain dole. For centuries, citizens of Rome received free or reduced price grain from the government. When this ended, there was no longer as much incentive to live in Rome.

Supposedly it was the first city in history to reach 1m people. I believe the second city to do so was London in around the year 1850! (Pls correct me if I'm mistaken)

1377-1527 Was the start of all those BOOMS.

Nowadays its 2.8M people.

and way back in 1084 it only had 15,000 people

Jeez man they probably signed the Constitution of 1377 that said more population
